=Wizardry and Steamworks=
 
Wizardry and Steamworks are a development group to be found in Second Life. The leaders of the group are [[User:Kira Komarov|Kira Komarov]] and [[User:Flax Quirina|Flax Quirina]]. We specialize on scripting in Second Life, however anything that pushes the boundaries of what is currently possible in Second Life is of interest to us.

=FUS (Frequently Used Snippets)=
 
Frequently Used Snippets (FUS) are short snippets that are generic enough to be included in any script. Just as you have generic types, generic functions, these represent an abstraction over Second Life script programming methodologies particular to Wizardry and Steamworks [WaS] and although they aren't delivered in the form of scripts, they can be used in any script by inserting them at the right places.
 
==Private Channel Key-Hash==
 
Extremely useful, taken from [[llDialog]].
 
'''Inline Usage'''
<lsl>
integer comChannel = ((integer)("0x"+llGetSubString((string) /* llGetOwner(), llGetCreator(), llDetectedKey(0), id */,-8,-1)) & 0x3FFFFFFF) ^ 0xBFFFFFFF;
</lsl>
==Endless Menu with Back and Next==
 
This generates an endless menu with Back and Next buttons by arranging a list dynamically whenever the Back and Next buttons are pressed. It has been used in several scripts with some variations.
 
'''Global Primitives'''
<lsl>
list menu_items = [];
list key_items = [];
integer mitra = 0;
list cList = []
</lsl>
'''Global Functions'''
<lsl>
list mFwd() {
    if(mitra+1>llGetListLength(menu_items)) return cList;
    cList = llListInsertList(llListInsertList(llList2List(menu_items, ++mitra, (mitra+=9)), ["<= Back"], 0), ["Next =>"], 2);
    return cList;
}
list mBwd() {
    if(mitra-19<0) return cList;
    cList = llListInsertList(llListInsertList(llList2List(menu_items, (mitra-=19), (mitra+=9)), ["<= Back"], 0), ["Next =>"], 2);
    return cList;
}
</lsl>
'''Inline Usage'''
<lsl>
            integer itra;
            for(itra=0, mitra=0, menu_items=[]; itra< llGetListLength(/* list */); ++itra) {
                menu_items += llList2String(/* list */, itra);
            }
            cList = llListInsertList(llListInsertList(llList2List(menu_items, mitra, (mitra+=9)), ["<= Back"], 0), ["Next =>"], 2);
            llDialog(/* Key to prompt */, /* Dialog Text */, cList, /* channel */);
</lsl>
 
==Generic Notecard Reader==
 
This is a generic notecard loader. In this variation, it does not set a timer to check whether the notecard has been loaded.
 
'''Global Primitives'''
<lsl>
key nQuery = NULL_KEY;
integer nLine = 0;
list nList = [];
//pragma inline
string nName = "New Notecard";
</lsl>
'''Reading'''
<lsl>
        integer itra;
        for(itra=0. accessList=[]; itra<llGetInventoryNumber(INVENTORY_NOTECARD); ++itra) {
            if(llGetInventoryName(INVENTORY_NOTECARD, itra) == nName)
                jump found_notecard;
        }
        llInstantMessage(llGetOwner(), "Failed to find notecard.");
        return;
@found_notecard;
        nQuery = llGetNotecardLine(nName, nLine);
</lsl>
'''Dataserver'''
<lsl>
    dataserver(key id, string data) {
        if(id != nQuery) return;
        if(data == EOF) return;
        if(data == "") jump next_line;
        list nList += data;
@next_line;
        nQuery = llGetNotecardLine(nName, ++nLine);
    }
</lsl>
'''Extension: Return if key/name NOT in nList'''
<lsl>
        if(!~llListFindList(nList, (list)/* llDetectedKey(0), llDetectedName(0) */)) return;
</lsl>
 
==RLV: Wearables & Attachment Lists as Strings==
 
A pain to type.
 
'''Local preferred, global if needed'''
<lsl>
//pragma inline
list CLOTHES = [ "gloves", "jacket", "pants", "shirt", "shoes", "skirt", "socks", "underpants", "undershirt" ];
//pragma inline
list ATTACHMENTS = [ "none", "chest", "skull", "left shoulder", "right shoulder", "left hand", "right hand",
                    "left foot", "right foot", "spine", "pelvis", "mouth", "chin", "left ear", "right ear",
                    "left eyeball", "right eyeball", "nose", "r upper arm", "r forearm", "l upper arm",
                    "l forearm", "right hip", "r upper leg", "r lower leg", "left hip", "l upper leg",
                    "l lower leg", "stomach", "left pec", "right pec", "center 2", "top right", "top",
                    "top left", "center", "bottom left", "bottom", "bottom right" ];
</lsl>
 
==RLV: Rotate Avatar To Face Target==
 
'''Primitives'''
<lsl>
vector targetpos = < /* x */, /* y */, /* z */ >;
</lsl>
'''Inline usage'''
<lsl>
        vector pointTo = targetpos - llGetPos();
        float angleTo = llAtan2(pointTo.x, pointTo.y);
        llOwnerSay("@setrot:" + (string)angleTo + "=force")
</lsl>
 
==Using [[llSensorRepeat]] as a Timer==
 
Can be used as a second [[timer]] event. Explained in [[User:Kira Komarov/Trick or Treat]].
 
'''Global primitives''';
<lsl>
integer flag = 0;
</lsl>
'''Starting the sensor-timer'''
<lsl>
        llSensorRepeat("", NULL_KEY, flag=1, 0.1, 0.1, 60);
</lsl>
'''(No) Sensor'''
<lsl>
    no_sensor() {
        if(flag) {
            --flag;
            return;
        }
 
        /* this area will be hit 60
          * seconds after the llSensorRepeat()
          * has been executed. */
    }
</lsl>
 
==Planar or Grid Distance==
 
[[File:WaS_Planar_Distance_Kitty_and_Book.png|400px|center|thumb|Distance is marked with red]]
 
The x,y planar distance between the kitty and the book is given by:
<lsl>
float length_of_red_primitive=llVecDist(<kitty.x,kitty.y,0>,<book.x,book.y,0>);
</lsl>
 
This works for all planes: (x,y), (x,z) and (y,z) by eliminating one of the components - in this example, z.
 
==Object Rotate to Face Object==
 
[[File:WaS_Kitty_Rotates_to_Face_Book.png|400px|center|thumb|The rotation required to be applied to the kitty object in order to face the book.]]
 
The rotation is given by qΔ.
<lsl>
vector book_position = <83.889717, 92.310814, 500.5>;
vector kitty_position = <82.306671, 92.310814, 501.714783>;
 
default {
    state_entry() {
        rotation qΔ = llRotBetween(<1,0,0>,llVecNorm(<book_position.x-kitty_position.x,
                                                      book_position.y-kitty_position.y,
                                                      book_position.z-kitty_position.z>));
        llSetRot(llGetRot() * qΔ);
    }
}
</lsl>
By eliminating a component x, y or z in [[llVecNorm]] the kitty may turn on only on certain axes.
